IMPROVEMENT IN OIL-0UP FOB. LU'BBIGATIN SHAFTS.

titty: fidgttrle ttfttttli in in that 532mm hermit ant making out of tin same.

, Be it known that we, Emmrcu JOSEPH GERDOM-nnd Cannons WILLIAM SCHINDLER, both of Albany, State of New York, have invented a new and improved Oil-Cup for the Journals of Shafts of Machinery; and we declare the following specification, with the drawings forming part thereof, to be a full and complete description of our invention. I

Figure 1 represents the cup in position, as attached to the box. of a shaft, the cup itself, with its tube, and the shaft-boxes, being in centre vertical section; the revolving oil-distributor and the shaft in fullbody.

Figure 2 represents the revolving oil-distributor in perspective.

Similar letters dcnote the same parts of the apparatus.

A is the oil-cup, of the usual form; 13, its tube, which extends downwards from the bottom of the cuptC, the top of the cup. Within the tube B there is placed a revolving shaft, S, consisting of three metal tubes,'t, (the number may be more or less, according to the quantity of fiuid to be passed.) The tubes are small, being in internal diameter usually about one-fourth of an inch. They are long enough to extend from about threefourths of an inch above the top of the tubeB to about one-fourth of an inch below its bottom. They are held together near the top by a disk or plate, a, secured to them so as to lie upon the bottom of-thc cup, and suspend them within the tube 13. At the bottom they are secured by a short band of metal, 5, soldered aroundthem, the band having its lower edge faced truly at right angles to the axes of the tubes. They are also held together by a wire, to, wound spirally from the disk to the band, which, besides binding them, hnsthe effect of carrying down regularly the oil that passes through orifices e (two of which are seen in the drawing) in the dish a, to and over the band I), to the journal of the shaft. J represents the journal of the shaft K, which is to be oiled D, the boxes and brasses. The tube 13 is to be entered through the usual opening, E, in the cap-plate of the box and upper brass, and lowered down untii the bottom of the band 6 rests upon the shaft K, but it must approach the shaft, not at right'anglcs to it, but with a slight inclination, so that the edge of the base of the band 6 shall touch it at one corner only, at :c. The object of this is to cause the shaft, by its motion, to revolve rapidly shaft S, the surface of K and the edge of b acting as bevel-gear, driving the smaller shaft with the velocity due to the difference of their respective diameters.

The oil-cup is intended to be used with stiff preparations or unguents of tnllow or fat, or any oil, animal or vegetable, it being undcrstoodthat such'compositions, when they can be used, are for more economical than the oils usually employed to lubricate machinery. The applicants of this patent prepare an unguent, the knowledge of whose composition they for the present retain to themselves, and for the proper use of which the abovedescribed apparatus was invented, and the employment of which they declare to result in alarge saving of cost, as compared with oil or tallow, or any lubricant now used,

The operation of the apparatus is thus: The cup, being filled with the lubricating-material, and dropped down in contact with the-journal J, the shaft S revolves with great rapidity, by its movement suflieiently warming the stuff, so as torender the portion near the tubes so fluid as to pass it in drops slowly through them, and through orifices e along the wire w, down to the journal J.

The nature of the composition they propose to use is such that its mass can never be rendered morefluid by the operation of the machine than topassn regulated quantity (enough, but without waste,) to the journal.

What we claim, and desire to secure by Letters Patent, is-

In combination withan oil-cup A, a shaft, S, constructed of tubes, communicating with the journal J, and rotated by the motion of the journal, substantially as and for the purpose described.
